The tabasco pepper is a variety of the chili pepper species "Capsicum frutescens" originating in Mexico. It is best known through its use in Tabasco sauce, followed by peppered vinegar.

The tabasco plant has a typical bushy growth, which commercial cultivation makes stronger by trimming the plants. The tapered fruits, around 4 cm long (1.5 inch), are initially pale yellowish-green and turn yellow and orange before ripening to bright red. Tabascos are the only variety of chili pepper whose fruits are "juicy", i.e., not dry on the inside.

The peppers are named after the Mexican state of Tabasco.
